You can set the default paper-size with a -d option in the LP command
line. See p10 of the "Usage" manual (2.19.80 page ref.).

BTW My experience is that A4 is the default paper size and I never gave
it any thought until the folks surrounding me talked about °F, inches,
pounds (weight) and letter paper. So there might be a locale setting
that's overriding things.
